Best Answer:Comes with three sets of lenses. Grey, Rose, and Yellow. I went mountain biking a few times this weekend. Wore the grey on the sunny day and switched to rose for the overcast day...these are sick!

Best Answer:First off; I am not a fan of super-dark lenses and these are not super-dark. I use the rose lenses for weekday ordinary conditions in Minnesota; driving, going out for lunch, etc.. I have also used these lenses in the mountains of Colorado on sunny winter (very bright) days without discomfort. The rose color doesn't seem to affect my color perception any more than gray or bluish lenses do.

The Spectra lens contains multiple layers of mirroe for a look that is equally unique as it is effective in full sunshine. Spectra mirrors keep bright light tined down and lets your wandering eyes go undetected.
